A 2-3 day window is reasonable for a session to be scheduled.
But the idea of posting polls outside of a designated window being illegal is not the kind of change I believe will help, a simple poll is enough to fix a political dispute if a citizen is allowed to post it, we've seen that twice in this DG, and as I recall both of those polls came very near to a scheduled play session, would they be illegal under this idea? Don't expect that a schedule for meta game actions will end all political disputes.
